Abstract (en)

[origin: EP3226637A1] The present invention discloses an indication information transmission method and apparatus. The method includes: determining, in one or more codebooks, a first codebook used to send a first downlink data stream to a terminal device; determining one or more second codebooks used to send a second downlink data stream; determining codebook indication information used to indicate the first codebook and the one or more second codebooks; and sending the codebook indication information to the terminal device. According to the indication information transmission method and apparatus in embodiments of the present invention, a network device sends, to a terminal device, codebook indication information used to indicate a first codebook and one or more second codebooks, so that the terminal device can determine codebooks used for all data streams carried on a same time-frequency resource, and can decode, according to the codebooks, a first data stream sent by the network device to the terminal device. In this way, the network device and the terminal device can perform downlink data transmission based on the codebooks, and a network capacity of a system can be effectively improved.
